To all whom t may concern:

Be it known that I, Homer: A. CURETON, a citizen of the United States,residing at Los Angelea'in tl .i county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Radiators, ofwhich the following is a specification.

This invention relates to radiators for internal combustion engines andparticularly pertains to that type of radiator known as honeycomb whichis cooled by the passage of air through air ducts.

It is an objecte of my invention to construct a radiator of the classdescribed which allows the circulation of water around air ducts at aslow rate of travel, the water being retarded in its How by the zigzagconguration of the channel through which it passes so that it will besubjected to-the cooling action of the air passing through rthe airducts a longer time than in radiators having straight water channels.

Another object is to provide a radiator construction which allows thewater to flow therethrough in a thin bod thus 1facilitatingthe coolingaction of t e air thereon.

i culatory It is a further object Vto so form the cirstemof my radiatorthat the air will come 1n direct contact 'with all the walls whichretain the water during its liow through the radiator.

It is another object to so form the water channels that they will havevertical and horizontal portions subject to the action of a current ofair passing through adjacent air ducts. Another object of my inventionis to form the vertical walls of the water passages and air'ducts at aninclination to the direction of iiow of air entering the ducts, so thatthe air in passing through the radiator will not simply pass throughunresisted but will ixnpinge against the inclined walls of the ducts',and in so doing increase the cooling action of the air upon the water toa con;

, siderable degree.

Another object is to so form ithe component parts of which the radiator1s composed that but one shaped element is required to build theradiator throughout, thus eliminating a number of special dies and theexercise of great care in :selecting the proper elements to produce thedesired radiator.

Other objects will appear hereinafter.`

- all,1as'shown in Fig. 2.

In forming the corrugations, a double rib-like wall 15 is formed betweenthe adjacent corrugations on the air side a of the sheet, as shown inFigs. l and -l. rl`his riblike wall is U-shaped in cross section withits inner faces spaced apart, as shown in Fig. 7, forming transversechannels 16 be tween adjacent corrugations on the water side of thesheet, as shown in Fig. 7. The edges of the walls 15 on the air side aof the sheet are on the saine plane so that when the air sides of a pairot the sheets are disposed face. to face, the rib walls on `one sheetwill seat on the rib walls of the other sheetI throughout their lengths.p

A eorrugation 21 is fornwd longitudinally of the walls 13 and 14 a nd ishere shown as substantially V-shaped in cross section. Thesecorrugat-ions bear the relation to each other and to the walls 18 and 14as shown in Fig. 7. In this figure they are shown as forming verticalpassage ways or water channels 17 which connect one set of channels 16,formed by the rib-walls 15, to the other. The corrugation 21 provides ameans of disposing of a surplus of metal which occurs during` theforming operation and also increasesthe water capacity of the radiatorover that of a straight wall channel, and furthermore increases theradiating suryi'ace and thereby aids in more readily coollng` the waterwhich flows therethrough.

he outer end of the bottom wall of each corrugation extends on the sameplane as the opposite end of the adjacent corrugation so that the sideedges of the sheet will be of substantially the'same thickness over- Asa meansfor providin a clearance or splce between a pair of t e sheetswhen p ced with the water sides b adjacent each other to form alongitudinally extending water channel 16` and 17, between the sheets,olf-sets 18 are formed in the walls 13 and 14 on the water side of thesheet, as shown in Fig. 5.

In assembling the radiator, a pair of sheets are placed with the watersides b against each other with the corrugations on one/sheettelescoping the corrugations on the other sheet, whereupon the end edgesof the s heetsare secured together in any desired `manner. This forms aradiator section substantially corresponding in shape toa single sheet,this section', however, having the lon` gitudinally extending-waterchannels 16 and 17 extending therethrough. y This water channel will bezig-za in its formation, that U is, the channel extending between thecontiguous inner walls 'df a pair of corru ations will extend diagonalto the spacer etween the inner Walls of theadjacent corrugation, asillustrated in Figs. 8 and 9.

pair of 'sections thus formed are then arranged side by side, as shownin Fig. 6,

forming a series of air ducts 'lll and 2O arranged so that adjacent airInria will extend in diagonal relation to rarh nini. py this arrangenwnlthe walls 11. and l forni diagonal iinpinging walls again# which ahr ',f

flowing through the ducts strike. :hereby effecting' a more rapidcooling :n-Lion than where, the side walls ot the ducts arranged in thedirection ol' the tlou' oi air entering the ends thereof.

In the operation oi' my radiator, the water passes vertically throughthe units. as indicated by the arrow c. through the water passages 1i',then extenfjling outwardly into the channels 1li and from there throughsucceeding passages 1i'. In this manner tinI uater will be subjected tothe cooling action of the air as it is impingcd against tlnA an gularsurfaces 13 and .lland also as it euvelops the walls of the channels 1".lt will thus bc seen that the film of water is acted upon by the coolingaction of the air against (all of itsl adjacent walls. and that thereare no portions of the radiator which come ir. direct contact. with thcpassing water that are not directly acted upon by the air passingtherethrough, the manner in which I have diagonally arranged the waterpas sages increasing the cooling effect of the air thereupon as itretards its passage therethrough and diverts its line of travel, in thisway throwing it more forcefully against the adjacent walls.

lIt will thus be seen that I have provided a radiator construction whichwill allow the water to pass therethrough at a slower rate of fiow thaniscommon, will subject a maximum volume of water to the cooling actionof the a-ir and insure that the air acting upon the radiating surfaceswill do its work more etiiciently than in forms of radiators where thepassage of air is unretardcd.
